A new double-curved arch bridge

A double-curved arch bridge, a new type of technology, applied in the direction of arch bridges, bridges, bridge forms, etc., can solve the problems of increasing the width of the bridge deck or the width of the red line of the route, the sense of oppression of the driving space on the bridge deck, and the visual opacity, so as to increase the beauty of the bridge. , The overall force is reasonable, and the effect of optimizing the vertical force

Abstract

The invention relates to a novel double-curved arch bridge. The arch bridge includes a main girder, a main arch rib, an auxiliary arch rib, a side suspender and a middle suspender. Both sides of the main girder are provided with a parabolic main arch rib. There are multiple parabolic auxiliary arch ribs between the two main arch ribs, the two ends of the main arch ribs (i.e. The main arch rib is fixed. Compared with the prior art, the present invention reduces the stress on the beam for wide bridges due to the addition of suspenders and auxiliary arch ribs between the parabolic main arch ribs, which is beneficial to reduce the height of the beam and control the width of the wide bridge. structure height.

Description

technical field

[0001] The invention relates to the technical field of bridges, in particular to a novel double-curved arch bridge. Background technique

[0002] When encountering a bridge design with a wide deck, the tied arch bridge is usually designed as a tied arch bridge with three bearing surfaces or two tied arch bridges arranged side by side. The size of the rib structure leaves 4-7m for the width of the bridge deck, which increases the width of the bridge deck or the width of the red line of the route, and the driving space on the bridge deck creates a strong sense of depression, which is visually opaque; and it is neither economical nor beautiful. Contents of the invention

[0003] The object of the present invention is to provide a novel double-curved arch bridge with more optimized stress and better economy in order to overcome the defects of the above-mentioned prior art.

[0004] The purpose of the present invention can be achieved through the following tech...
